Manchester City have been in great form of late, and much of it was down to the purple patch for Argentine striker Sergio Aguero. With eight goals and three assists in his last eight games, Aguero was on top of his game, and was helping Manuel Pellegrini's men cut the gap at the top of the Premier League table.
Yet just seven minutes into City's game against Everton on Saturday, Aguero went down clutching his knee, and was unable to continue. The 26-year-old was immediately substituted, and was helped off the pitch in tears after yet another injury setback.
There hasn't been an official timescale on how long Aguero will be out for yet, but reports in Spain suggest that it could be up to six months – and that leaves Pellegrini short of options in attack.
Edin Dzeko and Stevan Jovetic have been ineffectual at best this season, with the latter even enduring his own injury nightmare for the second season running.
With Alvaro Negredo out on loan at Valencia, City are down to just two fit strikers – and with Negredo seemingly ready to complete a permanent return to Spain, City may need reinforcements if Aguero is out long-term.
However, instead of attacking the transfer market – as City often do with their never-ending pot of gold – they could instead look to bring a striker back from a loan deal, and it isn't Negredo.
John Guidetti was sent off to Celtic on deadline day, loaned out yet again after previous spells with Burnley, Feyenoord and Stoke City.
The 22-year-old Swede was snapped up by former City boss Sven Goran Eriksson back in 2008, but has barely featured for City, largely due to either loan deals or a mystery virus which kept him out of action for over a year.
Now back to full fitness, Guidetti has been banging in the goals for Celtic, scoring 10 in 13 as he immediately became a hero to Bhoys fans.
The terms of the loan deal state that Guidetti will spend the entire season with Ronny Deila's side, but recent speculation over his future suggests that Hull City and Marseille want to sign him permanently, which would involve City recalling him before selling him on for big money.
However, maybe Pellegrini should instead consider recalling him in order to use him at the Etihad Stadium.
Guidetti is bang in form right now, and his predatory instincts have seen him succeed in the Netherlands and Scotland, which he could replicate in the Premier League if given a chance.
Guidetti's contract expires at the end of this season, and it would be remiss of City to simply let him move on without giving him a real chance in the first team – and with Aguero out injured and few other options in attack, this is the perfect opportunity for City to assess what they have in Guidetti.
